Hello all,
I want to give my ybr yamaha a little bit more topspeed, is that possible with a K&N or other filter?
The ybr does 55mph i want it to go 60mph.
I just gave it a new maintenance with fresh Castrol juice and iridium sparkplug.
I did also the valvejob and placed a new airfilter (original one from Yamaha)
the reason why i want a little more topspeed is because it is now very dangerous with the trucks.
Thanks in advance
